Brief description
This data set contains the stable isotope carbon values for plants surveyed by Australia’s Terrestrial Ecosystem Research Network (TERN) between 2011 and May 2022 (inclusive). This data was produced to assign a photosynthetic pathway for 540 species that had no recorded pathway. This photosynthetic pathway data set was created by TERN to enable research examining the abundance, richness, and distribution of C4 and C3 vegetation in Australia. The full details of photosynthetic pathway data can be found in the linked collection: Munroe, S., McInerney, F., Andrae, J., Welti, N., Guerin, G., Leitch, E., Hall, T., Szarvas, S., Atkins, R., Caddy-Retalic, S., Holtum, J. & Sparrow, B. (2020): The Photosynthetic Pathways of Plant Species Surveyed in TERN Ecosystem Surveillance Plots. Version 2.0. Terrestrial Ecosystem Research Network. (Dataset). https://doi.org/10.25901/k61f-yz90Lineage: TERN plant tissue samples were identified and selected using the ausplotsR package. Samples were selected for stable isotope analysis based on overall condition and availability (i.e. the amount of sample available from a given plot). A 2 g subsample of material was taken from each silica-dried tissue sample. Each subsample was placed in an Eppendorf tube with two small ball bearings and pulverised for approximately one minute at 30 htz using a Retsch Mixer Mill. If samples had not homogenised during this initial process, samples were transferred to a stainless-steel ball-mill grinder and were ground for a further one minute at 30 htz. An initial group of 378 samples were analysed for stable isotopes at both Mawson Analytical Spectrometry Services (MASS) Facility, University of Adelaide and the Stable Isotope Facility at the Waite Campus of CSIRO in 2019. A subsequent group of 162 plant samples were analysed in 2020 at MASS.
